Application October 26, 1950, Serial No. 192,239 11 Claims. ((31. 24-205 This invention relates to separable fastener stringers employing a slider for coupling and uncoupling the scoops of the stringers. More particularly, the present invention deals with devices of this type and kind, wherein the complete fastener is made from a single stringer tape folded centrally to bring end and/or side portions of the stringer tape in coupling engagement with each other.

The novel features of the invention will be best understood from the following description, when taken to: gether with the accompanying drawings, in which Fig. 1 is a plan view of a fastener made according to my invention, with parts of the construction broken away and in section;

Fig. 2 is a plan view of a modified fastener; and

Fig. 3 is a reduced partial view, partly in section, of the fastener of Fig. 2 showing the lower ends of the stringer in coupled relation.

In Fig. 1, I have shown at 1 an elongated stringer tape, the length of which will be substantially twice the length of an opening or section to be closed by the fastener. The stringer tape 1 has the conventional enlarged or beaded edge 2, to which is attached,'at spaced intervals, scoops 3 of the double action type, that is to say, scoops having both male and female coupling portions on opposed surfaces thereof.

Ends of he tape 1 are inwardly folded, as indicated at 4 and 5, and fixed to these inwardly folded ends is a box part 6 and pin part 7 of a separable coupling. The pin part 7 is insertable into the socket 8 of the box part and is stopped by the end Wall 9 of said box part, so as to aline the scoops 3 at one side portion 10 of the tape 1 with the scoops 3 on the opposed side portion 11.

The pin part 7 also preferably has formed thereon a scoop coupling head 12, which is adapted to mesh and interlock with the end scoop 3' on the side portion 10 of the tape. At 13 I have indicated the central portion of the stringer tape 1, which portion can be folded in the manner indicated or the central portion may be extended into an arcuate position, if desired. Joined to two adjacent scoops at the central portion 13 is a stop member 14, suitably fixed to the coupling ends of the scoops, as indicated at 15. The stop 14 maintains a slider 16 on the side portion 10 of the stringer or, in other words, in association with the box part 6.

The slider 16 is in the form of a conventional channelled slider body for reception of the scoops 3 in coupling the scoops on one side 10 with the scoops of the opposed side 11. The slider is shown of the pin lock type, wherein a pull 17 is pivoted to one wall of the slider, as at 18, the pull having a projecting pin or lock element 19 which passes through an aperture 20 in the slider wall to engage the scoops of the stringer to retain the slider in any position thereon when the side portions 10 and 11 are coupled together. This locking engagement of the slider with the stringer sides can take place at any desired position, so as to leave a large or small opening at the central portion of the stringer or substantteg patcnt 2,784,473 Patented Mar. 12, 195

be understood, however, that when the slider 16 is in abutting engagement with the box part 6, the pin 7 can be moved into coupling engagement through the slider 16, then into the channel or socket 8 of the box part 6, which brings the side portions 10 and 11 into proper alinement. Thereafter, the slider can be moved away from the box part to couple the scoops of the stringer sides 10 and 11.

. member 35 are attached to the inwardly folded end portions 36, 37 of the tape. It will be noted that the bar member 34and pin member 35 are each disposed adjacent and in contact with the end scoops 38, 39, respectively, on the tape. Note Fig. 3. The bar member 34 is provided with a projection 40, while pin member 35 has a groove 41 for receiving projection 40, and in this way the coupling members may be keyed together, as shown in Fig. 3, to prevent lateral movement of one relatively to the other. As is also shown in Fig. 3, when the coupling members are coupled together, the end scoop 38 is in contact with, and supported by, both coupling members 34, 35 to guard against turning of this particular scoop on the tape bead and to prevent possible mismeshing of the stringer ends.

The bar member 34 is associated with a movable box part or member 42 of the kind described and claimed in my copending application Serial No. 192,240 filed October 26, 1950, and also similar to those described and claimed in my co-pending application Serial Number 169,339, filed June 21, 1950, now Patent No. 2,649,688, issued August 25, 1953. For the purpose of the present invention a brief description of this box member may be useful. As may be apparent, it comprises a pair of upper and lower walls 43, 44 joined and spaced together by a web portion 45 and provided with upper flanges 46, 47, and lower flanges 48, 49. A pair of channels 42a and 4212 are thus formed which intersect above the web portion. One the upper wall 43 of the box member a pair of lugs 50, 51 are provided between which are disposed a movable lock member 52 and the hinge portion 53 of a pull 54. The lock member and pull are secured to the lugs by a pin or axle 55, and the pull may be tensioned to the box member by means of a spring,

not shown, as set forth in said co-pending applications. A recess 56 is formed in wall 43 through which the lock member is movable. As is described in the first mentioned co-pending application, the lock member 52 is actuated by the pull 54.

A slider stop member 57 is provided on the fastener having the disposition and construction as shown in Fig. 1. The slider 58 is also of the same type as in Fig. 1.

In its use as a bottom stop, the box member 42 may be regarded as associated with the bar member 34 to form a box part corresponding to the box part 6 of Fig. 1, and thus serves to receive the pin member 35 to form a separable end coupling. In such use, the box member will have the position shown in Fig. 3. As described in said co-pending application Serial No. 192,240, in order to prevent the box member from sliding off the lower ends of the coupling members and becoming disengaged from the fastener, interengaging means for box member 42 and bar member 34 are provided, according to which the inner surfaces of the walls 43 and 44 of the box member are each provided with a groove, one of 8. In combination, a single stringer tape having double acting scoops spaced longitudinally of one edge of the tape to form a stringer length, a coupling member at each end of said stringer length, one of said coupling members comprising a pin part and the other comprising a box part, said members, when the ends of said length are brought together, being couplable to and detachable from each other to form of said stringer length a pair of couplable stringer sides, a slider on said stringer length for coupling and uncoupling one stringer side to and from the other, respectively, and a slider stop member on said stringer length intermediate the ends thereof.

9. In combination, a single stringer tape having double acting scoops spaced longitudinally of one edge of the tape to form a stringer length, a coupling member at each end of said stringer length, one of said coupling members comprising a pin part and the other comprising a movable box part associated with a stationary pin portion, said members, when the ends of said length are brought together, being couplable to and detachable from each other to form of said stringer length a pair of couplable stringer sides, a slider on said stringer length for coupling and uncoupling one stringer side to and from the other, respectively, and a slider stop member on said stringer length intermediate the ends thereof.

10. In combination, a single stringer comprising a tape having double acting scoops spaced longitudinally of one edge of the tape to form a stringer length, a coupling member at each end of the stringer length, one of said coupling members comprising a pin part and the other comprising a box part, said box part being permanently secured to said stringer length and having means for releasably holding the pin part when the ends of said length are brought together to thereby couple said parts together, said members being couplable to and detachable from each other to form of said stringer length a pair of couplable stringer sides and slider retaining means intermediate the ends of the stringer.

11. In combination, a single stringer comprising a tape having double acting scoops spaced longitudinally of one edge of the tape to form a stringer length, a coupling member at each end of said stringer length, one of said coupling members comprising a pin part and the other comprising a box part, said box part being secured to one end of the stringer length and having means for releasably holding the pin part when the ends of said length are brought together to thereby couple said parts together, said members being couplable to and detachable from each other to form of said stringer length a pair of couplable stringer sides and slider retaining means intermediate the ends of the stringer.
